STEEL CAB-ROOF.

,To all whom it may concern:

Be it knownthat I, WALTER I. MURPHY, a citizen of the United States, and a resident of the city of Chica o, in the county of the strengthening of the roof and the prev on the ventio of sweating or collection of moisture imder side of the roof.

The invention consists in improvements in roofs ofthe type illustrated in niy Patent "No. 1,133,495, dated March\30, 1915', where in the r of sheets span the car from eavesto eaves an 'have their side margins flanged up and riveted together. The invention also consists in the end plate construction, andin the means of attachment of the roof to the side plates and end plates.

Further objects and details of the invention appear in connection with the following description of the several embodiments of'the invention illustrated in the accompanying drawings; and what the invention com rises is particularly claimed in the appen ed claims.

Fig. 10 is a longitudinal section of the roof shown in Fig. 9, taken at the eaves on the line 105-10 in Fig. 9, looking in the direction of the arrows;

Fig. 11 is a lon 'tudinal cross-section through the roof at t e ridge, further illus trating the modification shown in Figs.'9 and 10; and i Figs. 12 and 13 are detail views'of another modificatiqn of the invention, Fig. 12 being a transverse section of the roof at the ridge, showing a portion of the seam in side elevation, and Fig. 13 being a cross section of the same on the line 13-13 in Fig. 12.

11 Figs. 1 to 6 of the drawings, a roof embodying the invention is shown applied toga steel frame box car having Z-bar side plates 11, but it may be ap lied toother orms of car body. The en plate 12 is a pressed metal member having a vertical web portion 13 extending from side to side of the car and riveted to the corner posts 14: at its ends. The ends of the web 13 are offset outwardly to permit the end osts to lie flush on the inside with the inner face of the web. The top edge of the end plate conforms to the arched shape of the roof, and has a lateral flange 15 extending "inwardly under the roof and riveted to the portion of the vertical web 13 is flanged out and down to form a long hood 16 projectin out from the end plate across the middle 0 the end of the car. The hood has its greatest outward extent at the middle of the car,

and narrows in toward the corner posts. covers the upper ends of the end and the dependin' flange 18 of fits down outside 0 the outer'fl'anges of the" end posts'ut their top ends and 1s riveted thereto. The inner flanges of the end posts 17 are flush. with the inner faces of the end posts and web portion 13 of the end plate, reby wooden p ank 19,01 other st le end sheathing, can he laid flush against the inside of the corner posts and end posts up to the roof if desired. Preferably the top edge of the end plankinv 19 is spaced below the top of the hood 16 in order to provide tor ventilation at the end of the car.

The roof is made of heavy metal roof sheets 20 which are arranged crosswise of the car, spanning its 'width from eaves to caves, and supported at their eaves ends on angle iron eaves strips 21. The side margins of the roof sheets are bent up, forming straight flanges 22 along both sides of each sheet. The flanges 22 of adjacent roof sheets, are arranged in juxtaposition, and are covered by inverted U-shaped seam covers 23,.w1iich are riveted along their lower edges to thd flanges of the roof sheets. The seam covers extend from caves to caves, and their ends "are bent down over the ends of the joints between the roof sheets. The seam covers arejof varying height, being highest at the middle of the car and decreasing in height toward the eaves. The under surface ofthe roof sheets may be coated withv ground cork, magnesia, or other suitable heat insulating'. material, if desired.

The ends of the roof sheets are spaced above thimwps of the side plates 11, and pro ject over their outer edges. The angle shape eaves strips 21 have their-horirlontal flanges spaced above the side plates, with their vertical legs down, extending alongside of the vertical webs of the side plates on the outside thereof and riveted thereto, with a narrow space intervening. Spacing washers 21, which surround the rivets between the eaves strips and side plates, space the eaves strips away from the side plates in the construe tion shown in Figs. 1 to 6. This space between the eaves strips and side plates provides for ventilation, and permits water which may condense on the under sides of the roof sheets to drip off over the side plates.

At the ends of the car the roof sheets are spaced above and project over the tops of the end plates, and are riveted to angle iron end strips which extend across the end of the car outside of the vertical webs 13 ofthe end plates. The vertical legs of the end strips 25 extend down alongside of the webs 13 of the end plates, with a space intervening, and are riveted thereto. Spacing washers 26 may be used to maintain the end strips at a sufiicient distance from the end plate'to provide for ventilation under the ends of the roof. The spaces between the eaves strips .21 and side plates 11, and those between the end strips .25 and end plates 12, provide sufficicnt'.leeway to accommodate slight varia tions in the dimensions of the roofs and car bodies and permit the roofs to be readily applied to the cars by the use of spacing washers of suitable thickness.

The running boards 27 are arranged lengthw se of the car at the ridge, above the tops of the seam covers 23, and are securely The ends of the running boards project over.

the ends of the car and are bolted to plates :50, which are supported from the end plates '12 by means of brackets 31. The brackets 31 are bolted to the running boards and plates 30, and are riveted to the hood portions 18 of the end plates.

. In the modification of the'invention shown in Figs. 7 and 8, the eaves strip 32 and end strip 33 which support the edgesof the roof sheets 20 are angle irons, and have portions "34 of their vertical legs offset inwardly to bear against the vertical webs of the side plate 35 and end plate 36, thereby dispensing with spacing washers. The under surface of the roof is covered with a heat insulating lining 37 of paper or other suitable material, which is stuck on to the roof sheets wit glue or other adhesive substance.

In the modification shown in Figs. 9, 10 and 11, the top of the seam cover 50 is flattened out sidewise, and with the lateral flanges along the bottoms of its side walls, an I-section supporting member for the joint is formed which is light and strong. A double trough shaped pressed metal member 51, having its middle wall 52 of double thickness and extended up above the side walls, is arranged beneath each joint, with the middle wall riveted between the flanges 22 of the roof sheets 20. The ends of the troughs or channels project over the tops of the side plates, and empty into the spaces between the eaves strips 21 and the side plates. A lining of thin boards 53 is arranged beneath the roof plates. The boards 53 run crosswise of the car, their ends being supported on wood filler strips 54 which are bolted on top of the side plates. The lining boards 53 are supported at the ridge on the side flanges 56 of a channel shape ridge strip or purlin 55 which extends lengthwise of the car and is riveted to the under sides of the trough shaped ,members 51, as shown -in Fig. 11. p

In the modification shown in Figs. 12 and 13, the lining boards 53 run crosswise of the car and are supported at the ridge by rods 57, the ends of which are supported by hang, ers 58; These hangers are small metal plates which are riveted between the flanges 22 of the roof. sheets at the. middle of the car, and which project below the roof sheets and sheathin and have holes through them to atop.
